INTRODUCTION. iií. Reduce the area to bighas, multiply by 40 and divide by 121 ; find out acres, roods and poles. 6. To convert standard bigha into local bigha. The general rule is to find out the square of the fraction obtained by dividing the length in cubits of the standard katta, by the length in cubits of the required local katta and then to multiply the given area by the fraction last obtained. Bules in the case of local bighas dealt with in this book are given below : To convert into local bigha – (a) Of 5 cubits rod (ìwgga)---multiply by 16 and divido by 25. 121.
